11 Claims. (Cl. 105-409) Matter enclosed in heavy brackets appears inthe original patent but forms no part of this reissue specification;

'sills are employed which extend from end to end of the cars. The sidesills in the case of house cars which have wider than usual dooropenings as in automobile box cars and some box cars, are reinforced bymeans of 15" 40:9: channels whose upper flanges are riveted to thehorizontal legs of the side sills. The reinforcing channels extendacross the door openings and for a sufficient dis- The vertical legs orthe 3 legs are disposed vertically.

In this construction a further reinforcement is provided at and adjacentto each door post 'by means of a gusset formed from a flflplate securedto the door post by seven rivets in single shear arranged in a verticalrow and to the ver 'tical leg of the side sill by twelve rivets insingle shear arranged in two horizontal rows. Also the door post issecured to the vertical leg of the side -sill by two rivets which areindependent of the gusset.

Frequent failures occur in these cars embodying this construction.Fractures develop in the 2 vertical leg of the side sills adjacent tothe forward door posts beginning at the top edge and "extendingprogressively through the reinforcing channels.

The rivets securing the gussets and the door posts to the vertical legsof the side sills particularly adjacent to the forward door posts workloose or are sheared. Andthe rivets securing the reinforcing channels tothe horizontal legs of the side sills work loose with consequentdevelopment of fractures in the horizontal legs of the side sills andupper horizontal flanges of the reinforcing channels between the rivets.

. It is the prime purpose of this invention to overcome thesedifiiculties of present day construction of box cars.

A further object is to provide a construction for house cars which shallincrease the strength of the side sill structure at the door openinadjacent to the door posts.

A further object is to provide a construction for house-cars which shallincrease the strength of the connection of the side sill structure tothe carside construction at the "door posts.

line 34- 1 Fig. 7 is an eleoaiional view ofthe reverse side I of Fig. 1.

In the drawings a preferred embodiment of the invention is shown at thelower forward'portion of a door opening Ill formed in the side II of arailway house car. While the invention is illustrated only at the lowerforward corner of the door opening, it is preferred that it be utilizedas well at the lower rear corner of the, door opening. Since theconstruction embodying the-invention is similar at both of these cornersof the door-opening, it is not believed to be necessary to illustratethe construction at the lower rear However, this construction Thecarside ll embodies a front door post 12 which comprises a Z-shapedmember so arranged that its web I3 extends longitudinally andsubstantially in the plane of the carside, its flange [4 extendingoutwardly and its flange l5 extending inwardly. The door postillustrated also comprises an angle member I6 having an inwardlyextending leg I1 secured as by means of rivets l8 to the flange I5 ofthe Z-shaped member l2 and a longitudinally extending leg l9 which is inalinement with the web I3.

The carside also embodies an angle side sill having a verticalupstanding flange 2i and a horizontal inwardly extending flange 22.Within the door opening the upstanding flange 2| is cut "down inheightasindicated at 23 so that it terminates substantially in the upper planeof'the car floor 24. The side sill 20 extends substantially from end toend {of the car and is reinforced across the door opening and for asufqficient'distance beyond each side of the door opening by means of achannel member 25 arranged with its web 26 vertical and upper and lowerflanges 21 and 28 extending inwardly. Metallic sheathing 2,9 formspartof the carside and is secured by means of riveting to the web 13 of thedoor post 12 and to the upstanding leg 2| of theside 58111.

"In orderto adequately reinforce the construction hereinabove d scribedat a jacent t thedoor opening, the instant invention utilizes inner andouter gusset members 30 and 3 I. The inner usset member 39 is' ecured othe inner dace of'the web l3as by means of rivets 32 and to' he innerface of the'lon i udinally extendin leg 19 asbymeans of 11ivets33- Theinner u set member 30 isseoured to the inner fa e of th upstandin fl n e2| of th side ill y m ans of a do ble ow of rivets 5- The lower marginof theinnergusset member is provided with an inwardly extendin hor z l ne "w ich is secu d a by me n of rivets :36 to he ho ontal flan es :22and .21 of the side sill and side sill reinforcement, respecii smoreoiearly shown in Figs 1 and 5 f the dr ,wi es. the ;h rizontal lange.5 of th e as; set m mb r is ext nd d into th d or op n-i sand w thinthe enin t i n r usset member is cut down in height as indic ated at :31so it lies s hstoh i i iin e up er plane of the car floor. (See Fig. 4).

The outer gusset mem er S is se ured y means of the rivets 32 and 33 tothe outer face Zofwthe web 13 and leg is, respectively, and to the innergusset member 30 thereby placihgthe "'rivlets 32 and 3:3 in doubleshear. The outer gusset member 3| is also secured by means of the rivets'534 tothe outerface of the upstanding flange 2| of the side sill. Thusthe rivets 34 which also secure the inner gusset member 30 to the11pstanding flange 2| of the side sill are placed in double "shear.

*Theouter gusset member '3! beyond the door openingis extendeddownwardly as indicated at -38 andis secured-as by means of'riye'ts 3 9to the-outer face of'thewebzli of the sidesi-ll reinforcement.

The outer gussetmember is also extended along the door opening'l II asindicated at :40 and is also secured .to the .outer'face of the web ofthe side sill reinforcement as by means of rivets-.5]. The latterextending portion of the outer gusset -member-terminat'essubstantially-in the upper of the side sill by means of the rivets 34which secure the extending portion of the inner gusset member to theinner face of the flange 2 I.

By virtue of the invention the moment of inertia and the section modulusof the carside construction has been substantially There has beenobtained also a substantial increase in the v hickness of theconstruction in the door opening inasmuch as the inner and outer gussetmembers are extended into the door opening. Moreover, the constructionis such that the securing '{ri-vets are placed in double shear.

To avoid conflict between the inwardly extending flange l5 and leg I! ofthe door post and the inner gusset member 30, the flange l5 and leg I"!are terminated above the gusset member as indicated at 43 and 4.4. Theweb l3 and the iongitudinal leg l9 are continuous, however, and areextended so as to terminate above and adjacent to the upper edge-of theupstanding leg 2| or the 'side'sill as indicated at 45 and 46, While theweb I3 is coped as indicated at 41 to conform to :the cope 48 in the leg2!, the outwardly extending flange M of the Z-shapedmember of the doorpost is extended downwardly below the door opening as indicated at .49and is preferably welded'to the outer gusset member 3|.

To compensate for the loss of strength resulting from the removal of theinwardly extending flange I5 and leg I1, a plate member 50 is'disposedbetween and secured as by means of rivets 5| to the inwardly extendingflange l5 and leg 11 as shown more clearly in'Figs, 1 and 3 of thedrawings. For this purpose the angle member It is oilset as indicated at52. The reinforcing plate member 50 is extended downwardly to theinwardly xtendin flan .35 of the n e gusset member to "which it issecured as by means of welding. The offset 53 formed in the reinforcingplate member 50 is for the purpose of avoidins con lict between this ebe d h r et sion from the vertical rivets which secure the horizontalflanges of the side sill and side sill reinforcement together. Thestress to which these rivets 'are subjected is essentially a shearstress whose unit valu is materially reduced since they are placed indouble shear by being driven through the horizontal flange of the innergusset member.

It will be understood that the disclosed invention is'no't limited tothetype of door post i-llustrated in the drawings but is capable of usewith the various types of door posts employed in house carconstructio'n.For example, the door posts "may be formed of the Z-shapedmember alonewithout the separate angle member, or of a w-shaped member, or thesubstantiallychannelsshap'ed A. A. 'Rytype door post may be used. Again,any of the known types of Welded door posts may be utilized, such as thedoor post formedof .a channel-shaped member and a plate member plain orflanged, the channel-shaped member having unequal legs and disposed withits web parallel to the car side and-its'fiangs increased.

directed outwardly and the plate member lying in the plane of the carside and welded to the edge of the shorter leg and to the longer leg inspaced relationship to the edge thereof. The channel member of thewelded door post may be replaced by a flanged plate member whose flangeslie parallel to the car side. In the latter construction the firstmentioned plate member of the door is welded to the latter plate memberas described above.
